A ton of people pair Unions with the Evo. I personally don't like their toe straps and ratchets. Although they said they changed them for the production model (I demoed pre-production).
Based on the floor models in the shop a month ago, Union toe caps aren't significantly different than what you might have seen at a demo or trade show. At the very least, if they did improve them, they have a ways to go. The caps are still way too thick to really conform to the toe shape of the boot. What K2 has done with The Company/Uprise and Rome with their Conformist caps are solid alternatives if you don't happen to be in on the TechNine/Burton Baltimore toe cap patent.
The 2012 Union caps would be so improved if they were closer to what Raiden has on theirs. It's the same basic design, but the execution is much better.
Flux bindings all the way. I am a convert after winning a contest here, and today I handflexed some at my local shop. Sweet bindings and amazing materials/quality/workmanship.
I think its a bit premature to recommend bindings that you have never used. I'm sure when you actually do test them out, you may like them, but its a bit asinine to recommend bindings because you won a contest and look good in a shop.
